Hi, i am trying to implement a simple gstreamer application with nim, but I need some help: This is the C code
#include <stdio.h>
#include <gst/gst.h>
int main(int argc, char **argv)
{
const gchar *nano_str;
guint major, minor, micro, nano;
gst_init(&argc, &argv);
gst_version(&major, &minor, µ, &nano);
if (nano == 1) nano_str = "(CVS)";
else if (nano == 2) nano_str = "(Prerelease)";
else {nano_str = "";}
printf("this program is linked against GStreamer %d.%d.%d. $s\n",
major, minor, micro, nano_str);
return 0;
}
import std/os
type
guint = uint32
gchar = char
proc gst_init(argc: ptr cint, argv: pointer) {.header:"gst/gst.h", importc:"gst_init"} # this was done by me I guess something is wrong here
proc gst_version(major, minor, micro, nano: ptr guint) {.header:"gst/gst.h", importc:"gst_version"} # this also
proc main*(argc: cint; argv: cstringArray): cint =
var nano_str: cstring
var
major: guint
minor: guint
micro: guint
nano: guint
gst_init(unsafeAddr(argc), unsafeAddr(argv))
gst_version(addr(major), addr(minor), addr(micro), addr(nano))
if nano == 1:
nano_str = "(CVS)"
elif nano == 2:
nano_str = "(Prerelease)"
else:
nano_str = ""
echo("this program is linked against GStreamer %d.%d.%d. $s\n", major, minor,
micro, nano_str)
return 0
if isMainmodule:
discard main(cast[cint](paramCount()), nil)
